designated by the Filesystem Hierarchy Standard for locally-installed software - for example /usr/local/bin/ for binaries, /usr/local/src/ for source code, and so on. To allow system administrators to easily change the preferred location of various resources without the need to modify multiple roles separately, the debops.fhs role is a central place which defines base directories for other roles to use.

The base directories are created by the role, and a special /etc/ansible/facts.d/fhs.fact script is generated on the host. It serves dual purpose - the facts are used to ensure that any changes in the directory paths don't affect existing installations, and can be used by other Ansible roles to define various resource paths in their variables.
